CAS or MAS 711 + MRM-01 sensor connections
The CAS monitoring system has been replaced by the MAS 711. This section provides information for
connecting CAS to 6X5, 7X5, 8X5 and 9X5 drive units in the following situations:
• A replacement pump is being installed at an older pump station, where the CAS system is still
functioning.
• A replacement monitoring system is needed at an older pump station, where the pump is still working
but the CAS system must be replaced.
The CAS monitoring system is no longer available as a spare part. If a replacement for CAS is needed at an
older pump station, then the MAS 711 plus the MRM-01 relay may be used.
